The P90X nutrition plan is a 90 days program that emphasizes on healthy eating habits and proper physical fitness activities. A good combination of both these factors ultimately results into losing weight and muscle building. Correct adoption of this diet plan regulates your rate of metabolism, and increases you energy level and physical endurance. This diet plan is divided into three phases. Phase 1 is fat shredder (day 1 to day 28), phase 2 is energy booster (day 29 to day 56) and phase 3 is endurance maximizer (day 57 to day 90).
